1. A method for securely communicating with electronic meters, said electronic meters being communicatively connectable to an intermediary server controlled by a utility, said utility providing a service associated with said electronic meters, said method comprising:

  • a cryptographic backend system comprising one or more cryptographic servers receiving a first request from said intermediary server to cryptographically process a first message to be sent to an electronic meter;

    said cryptographic backend system cryptographically processing said first message to generate a first protected message according to requirements associated with said first message and using one or more cryptographic keys associated with said electronic meter;

    said cryptographic backend system returning said first protected message to said intermediary server for providing said protected message to said electronic meter;

    said cryptographic backend system receiving a second protected message from said intermediary server, said second protected message having been generated by said electronic meter cryptographically processing a second message, and having been sent by said electronic meter to said intermediary server;

    said cryptographic backend system determining one or more keys associated with said electronic meter;

    said cryptographic backend system cryptographically processing said second protected message to obtain said second message; and

    said cryptographic backend system returning said second message to said intermediary server to enable said intermediary server to interpret said second message.
